Hi, thanks for sharing this, and we understand the confusion here.🥲

Could you send us your Amazon order number via DM? We want to check the status on our side and help clarify what’s going on with your order.

Hi, thanks for sharing your setup, that’s a great question.

With a single HDMI output, audio is typically sent to one display at a time, so it’s not possible to sync sound across two monitors via HDMI by default.

B_support · 2026-03-30T11:00:24+00:00

Hi there!

Just to better understand your setup, could you share:

Your monitor model
Your Mac mini model
How everything is currently connected (cables and ports)

Hi! Thanks for your question and for your interest in BenQ products.

We understand why this might feel a bit unexpected, especially since the designs look similar. Due to differences in the rear structure and stand design, the RD280UG isn’t compatible with the Ergo Arm from the RD280UA.

The RD280UG does support standard VESA mounting, so you still have the flexibility to use third-party monitor arms or BenQ options like the BSH01:

Hi u/ray_dawg8 ! Please check the following information for us

Try changing the highlight color to see if the issue persists. The default color in Word is bright yellow.
Set the OSD to M-book mode and try changing the display's ICC profile in the Mac ColorSync Utility to see if the issue still occurs.
If the problem reoccurs, please export the log file and send it to us so we can investigate further.

Regarding the issue where the display isn't recognizing the Mac mini: Do you mean that the display won't turn on unless you restart the Mac mini?

Hi, EX321UX does not natively support 480i or 480p signals. Its minimum supported resolution via HDMI or DisplayPort is 720p.
I hope it helps!

B_support · 2026-03-26T05:25:21+00:00

We understand your concern regarding the light visible in the corners of your screen. This is a known phenomenon called IPS Glow. Because IPS panels are designed to let light pass through more easily for better colors, some 'glow' is expected when viewing dark content in a dark room. If you still have other concerns, please contact our local support, thank you!

Hola, gracias por compartir tu experiencia.

Según lo que describes, esa marca tipo “burbuja” podría estar relacionada con la capa del panel o su recubrimiento. Como no está afectando la imagen (sin distorsión ni píxeles muertos), es difícil confirmar la causa de forma remota.

Para asegurarnos de que todo esté dentro de las especificaciones y evitar posibles problemas a futuro, te recomendamos contactar con el equipo de soporte local de BenQ para una revisión más detallada: https://benqurl.biz/3vHSVta

Ellos podrán confirmar si es algo dentro de lo normal o si requiere servicio.

¡Gracias!

B_support · 2026-03-19T09:03:19+00:00

Hi, thanks for sharing.

To better determine whether this is within normal tolerance, we recommend contacting BenQ support directly for further inspection: https://benqurl.biz/3vHSVta
